Key Parameters

Substitute Part Grouping Explanation

Substitution of the 552726-1 connector is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Number of positions: 50
• Number of rows: 2
• Connector style: Center strip contacts
• Contact finish: Gold at 30.0µin (0.76µm) thickness

Mechanical Parameters:

• Connector type: Plug
• Mounting type: Panel mount, through hole, right angle
• Termination method: Solder
• Flange feature: Tapped, threaded (4-40)
• Series: CHAMP .085

Compliance Parameters:

• ECCN: EAR99
• HTSUS: 8536.69.4040
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 5552726-1 maintains identical electrical and mechanical specifications while differing in product status (active versus obsolete) and packaging configuration (tray versus unspecified). The substitute part also demonstrates improved compliance status (RoHS compliant versus non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The 5552726-1 connector is a direct functional equivalent to the 552726-1 across all electrical and mechanical parameters. Selection between these parts is determined by the following factors:

Product Status Consideration: The 552726-1 is classified as obsolete, while the 5552726-1 is active. For new designs, system upgrades, or long-term production requirements, the 5552726-1 is the appropriate selection due to its active product status and continued manufacturer support.

Compliance Status: The 5552726-1 is RoHS compliant, whereas the 552726-1 is RoHS non-compliant. Applications subject to RoHS regulations or customer requirements mandating RoHS compliance require the 5552726-1.

Inventory and Availability: The 5552726-1 demonstrates higher inventory availability (1450 pieces) compared to the 552726-1 (952 pieces), supporting supply chain continuity.

Packaging Configuration: The 5552726-1 is supplied in tray packaging, which may affect handling, storage, and integration into automated assembly processes compared to the unspecified packaging of the 552726-1.

Frequently Asked Questions (FAQ)

Q: Are the 552726-1 and 5552726-1 connectors electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 50 positions, 2 rows, center strip contacts, and gold contact finish at 30.0µin thickness. They are electrically interchangeable in applications where the connector interfaces with mating D-Sub receptacles.

Q: Can the 5552726-1 be used as a direct replacement for the 552726-1 in existing assemblies?

A: Yes. The 5552726-1 is mechanically and electrically equivalent to the 552726-1. Both feature identical panel mount through-hole right-angle solder termination, tapped threaded flange (4-40), and CHAMP .085 series specifications. Direct substitution is supported without design modification.

Q: What is the significance of the product status difference between these parts?

A: The 552726-1 is classified as obsolete, indicating that TE Connectivity AMP Connectors no longer manufactures this part. The 5552726-1 is active, meaning it is currently manufactured and supported. For applications requiring long-term availability and manufacturer support, the 5552726-1 is the appropriate selection.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory and environmental specification, not a functional compatibility parameter. Both connectors perform identically in electrical and mechanical applications. However, applications subject to RoHS regulations or customer specifications mandating RoHS compliance require the 5552726-1.

Q: How does packaging affect the selection between these parts?

A: The 5552726-1 is supplied in tray packaging, which is standard for automated assembly and high-volume production environments. The 552726-1 packaging is not specified. Packaging selection depends on assembly process requirements, handling procedures, and storage infrastructure. Tray packaging is generally preferred for automated pick-and-place operations.

Q: Are there any electrical performance differences between the two connectors?

A: No. Both connectors maintain identical electrical specifications including contact finish type, contact finish thickness, and all electrical parameters. Performance in signal transmission, impedance, and electrical reliability is equivalent.

Q: What is the REACH status difference, and does it matter for substitution?

A: The 552726-1 is listed as REACH affected, while the 5552726-1 is listed as vendor undefined. This difference reflects regulatory documentation status rather than functional capability. For applications in REACH-regulated regions, clarification with the manufacturer regarding the 5552726-1 REACH status is appropriate.
